`section of the vertical pipe 9. The fitting 15 with a central opening18 terminates Vat it-s upper end in a conical valve seat 19. Adapted forreciprocatory movement within the casing 13, is the valve 29. r1`hisvalve 2O is preferably formed o'f copper and has its ends rounded, as isclearly shown in Figure 2 of the drawings. rlhe lower end of the valve20 is adapted to seat on the valve Vseat 19 provided at the upper end ofthe fitting 15 when in one position, and to limit the upward movementofthe valve 20 within the casing` 13 I provide a cross piece 21 adjacentthe upper end kof the casing 13.

Ordinarily, with the hot water circulating systems now in use, when `itis desired to draw off hotv water from the tank, a person has to wait afewk minutes in order to enable the cold water standing in the piping topass through the outlet pipe before the warm water reaches the spigotlor faucet. In the arrangement as shown in VFigure 1 of the drawings,the necessity of having to 'drawoff the cold water first is eliminatedsince warm water willl at all times be within the circulatingr pipe sothat upon opening the faucet, a current of hot water may be immediatelyobtained.V VNormally, the valve 2O is held out of engagement with thevalve seat 19 due to equal pressure being placed on both sides of thevalve so that a continuous circulation of water from the tank 1 to thetop thereof and through the pipe 6 and finally through the bottom of thetank will he provided. In this manner, warm water at all times isycirculated through. the pipe 6 and through the boiler 1, it beingunder# stoodof Vcourse that the tank is initially When the faucet 12 isopened, the back pressure on the valve 2O will 'cause the sameV to seatagainst the valve seat-19 preventing a downward iiow of water throughthe pipe 9 thus preventing any cold water from entering the pipe andcausing the warm water to rise through the pipes 4, 5 and 6 and to bedrawn off finally by the faucet 12.

ln Figure 3 of the drawings, a similar arrangement is shown wherein thecirculating pipe 22 is connected to the top and bottom of a water tank23. A valve casing 24 y is associated with the circulating system and isarranged horizontally and disposed in the horizontally extending sectionof pipe 25, in the manner clearly shown. The circuvlating pipe 22 isprovided with the usual drain faucet 26 in the vertical section thereof. vThe valve casing 24 has its inner end which is substantially ,ofthe same construction as the fitting 18 heretofore described andprovided with the valve seat 28 and the internally threaded portion 29for'connection with the horizontal pipe 25. The fitting 27 is providedwith the central open- 1ing 30 similar to the opening 18 provided in thefitting 15. The opposite end of the valve casing 24 is provided with anextension 31 which is also internally threaded' for coniiection to thevertical section of pipe 32k extending from the bottom of the water tankrThe extension 31 is preferably arranged adjacent the outer end of thevalve casing 24 and adapted to be threaded into the outer end of thevalve casing 24 is the closure plug 33.

The valve casing 24 is also substantially tubular in cross section asshown 1n the and arranged -in spaced relation are the guides 34. Theseguides are arranged preferably adjacent the inner end of the yvalvecasing and are adapted to cooperate with the valve seat 28 of thefitting 27 in permitting the valve 35 which is in the form of a ball totravel in the casing in such a manner as to permit the valve to readilyseat against the .valve seat 28 when in one position and to engage thestop 36`when inthe other position. In F igure 4 of the drawings,` astill fur# ther modification of the valve is shown wherein thehorizontally disposed valve casing 37 has its respective ends connectingthe horizontal sections of pipe 38, the latter being connected tothevertically extending section of pipe 39 which communicates with thebottom of the water tank 40. The closure plug 41 associated with theyvalve casing 37 is preferably threaded into the extension 42 formed onthe upper portion of the Vvalve casing 37 adjacent the ends thereof. Thevalve structure associated withY the valve casing 37 is identical withthe valve structure shown in Figures 6 and 7 and it is not thoughtnecessary to describe the same.

' The operation'of the valve 35 within the valve casing 24 issubstantially the same as the valve action in the case of theverticallyarranged device shown in Figures 1 and 2 of the drawings, and heretoforemore fully described.

It will thus be seen from the foregoing water will be caused to passthrough the y water tank and through the circulating pipe so that aperson does not have to wait in order to obtain. Warm Water- The.Simplicity of my device enables the same to be readily assembled anddoes not require any attention on the part of a person desiring hotwater nor is any mechanical means necessary in order to prevent the coldwater which is always in the bottom of a water tank from beingdischarged through the faucet.

IVhile I have shown the preferred embodiment of my invention, it is tobe understood that various changes Ain the size, shape and arrangementof -parts may be resorted to without departing from the spirit of theinvention and the scope of the subjoined claim.

Having thus described my invention, what I claim is:

A water circulating system comprising a tank, a water supply pipeleading into the tank and terminating adjacent the bottom thereof, awater circulating conduit connected at its upper end to the top of saidtank and connected at its lowerend to the bottom of the tank, a portionof said conduit being disposed on a level below the bottom of the tank,a house supply pipepcommunicating with said circulating conduit, a checkvalve in said circulating pipe adapted to prevent the flow of water fromthe bottom of the tank through said conduit, and a water dischargespigot for the tank also in the circulating conduit, said spigot beingdisposed below the bottom of the tank, and said check valve beingdisposed between the spigot and the bottom of the tank. f l Y Intestimony whereof I affix my signature.
